SPLIT 1\TUT.

T0 all wkom z't may concern:

Be it known that I, HARRY C. PELTZ, a citizen of the Unitecl States, residing ab Lansford, in the county 0f Carb0n and St-ate 0f Pennsylvania, have invented certain neW and useful Improvements in Split Nute; and I d0 cleolare the following t0 be a fu1l, clear, and exact description of the invention, such as will enable others skilled in the art t0 which it appertains to make und use the same.

This invention relates t0 new and usefu1 improvements in locks f0r split nuts, and the primary object '0f the invention is=to provide an improvecl split nut adapted t0 slide freely upon a, threaded stem 01' rocl und Which embodies means f0r securely locking the nut atvarious positions thereon.

Another object 0f this invention is t0 provide a device 0f this character Which is simple und durable in construction, inexpensive 110 manufacture, and one Whi0h Will be very eflicient in operation.

WVith these and numerous 0ther objects in view, my invention consists of the n0vel features of construction, combination and arrangement of arts which Will be herein re ferred t0 and more particularly pointed out in the specification and elainns.

In the aecompanying drawings:

Figure 1 is a sich elevation of a take-up frame sh0wing the sp1it nut applied theret0;

Fig. 2 is an end elevation 015 the nut;

Fig. 3 is a longitudinal section 0f the nut;

Fig. 4 is a vertical section taken 0n the line e14 0f Fig. 3; and

Fig. 5 is a detail secti0n through the 100king ring showing the arrangement 0f the s1ots.

In describing my inVention I sha1l refer t the drawings in Whi0h similar reference characbers designate corresponding parts throughout the several views. In the accompanying drawing, I have shown a pair of these nuts applied to a take-up frame F, Fig. 1 showing the position 0f the nuts 011 the threaded bolt 0-n both sides of the frame.

The nut is formed of two semi-cylindrical sections 1 and 2, Which vare internally threaded as shown at 3, the threads being either right 0r lefthanded according t0 the direction in which it is desired the nut t0 turn. These two semi-cylindrical sections are adapted 130 be positioned 0n opposite sides 01 the threaded holt 4 and when so po- Specification of Letters Patent.

sitioned there Will be a space left between the adjacent -edges 0f the same es clearly shown in Figs. 2, 8 am]. 4 0f the drawing Owing 110 the faet that the nut is f0rmecl of these tw0 sections, the same may be quickly positioned 011 the holt ab any desired point, by merely placing the tw0 parts in opposed osition when desired.

One portion of the 0uter surface 0f the sections 01 members has a fiat sided head 5 formed thereon adjacent 0ne end, whilethe other portion 0f the outer surface is s1n00t-h as shown at 0 and slightly reduced t0 fo'rm a shoulder 7 where the inner end 0f this portion abuts bhe flat side 0f the head. The seetion 1 is provided with a laterally projecting stud 8 f0r a purpose t0 be hereinaft-er fully deseribed.

When the two semi-cylindrical sections 1 and 2 are positioned 0n the threaded b01t, they are locked thereon by means 0f a sleeve 9 which is adapted 110 surround the smooth ortion 6 of the outer surface 0f these sections 01' members, and t0 securely hold the same together. This sleeve 9 is provided With an annular recess 10 berein spaced fro1n one edge, and the recess 10 commuinicates With the end of the s1eeve by means 0f a longitudinal assage 11 lohnt extends from 0ne end t0 the recess. By this means when it is desired 130 place the sleeve upon the reduced portion 0f the nut, the 111g 8 is positioned within the recess 11 and the sleeve is s1id along the nut unti1 its end abuts against the shoulder 7 of the head portion. When in this position the lug 8 is passed through the recess 11 to the recess 10, whereupon by turnin i7he slaeve, the same Will be securely locke 011 the nuf Fr0xn the foregoing description it will be obvious that 0Wing to the fact that the nut is formed 0f two sections thab are detachable, the same may be placed at vario-us positions along the threaded shaft, and when placed at the desired point, in the locking s1eeve 9 engages the reduced portion 0f the nut, the tw0 sections 01 members Will be securely clamped t0gether and the nut may be tightened against the surface against Which it is supposed 110 bear. The annular recess Which coacts With the 111g 8 securely holds the locking sleeve 9 in osition, and prevents the Same from becoming disengaged from the reduced portion 0f the members which it surrounds. As herein illustrated the split nut is shown aPplied to a tzike-up frame but 113 1s adapted for numeruus us0s whare 1t 1s des1red t0 qmckly tra:verse the threadecl holt. 9

From the foregoing description of -the construcb1on und opemt1on 01 my nnproved nut, the manner 0f applying the sametm use, andifihe operzttion thereof Willbe readily undqrstood, and it Will-108 seen that Ihave prov1ded a simple and elficient device 0f this -character for carrying out'the objects of the mvenb1on.
